Overview
Achalasia should be differentiated from mechanical obstruction or neoplastic infiltration of lower esophageal sphincter which can present with similar symptoms such as dysphagia, regurgitation and weight loss. Endoscopic ultrasound is required in cases where malignancy is suspected.[1]
Endoscopic Ultrasound
Endoscopic ultrasound (EUS) is indicated in cases of achalasia like picture with strong suspicion of malignancy. Presence of following risk factors raises suspicion for malignancy:
- Elderly patients
- Short duration of dysphagia history
- Significant weight loss
- Unusually increased resistance to passage of endoscope through gastroesophageal junction
Unusual thickening of gastroesophageal junction, mass lesions or neoplastic infiltration revealed on EUS suggests diagnosis of pseudoachalasia instead of achalasia.[2]
